This Halloween week, there are no tricks, all treats, courtesy of a slew of your favorite musicians back with long-awaited new music! I'm not quite ready for the sequel to the Top 20 Songs of Summer yet (give me just a few more weeks...too many good tunes to sort through!), but in the meantime, I've been lucky enough to preview some of the fresh new music coming out this week...and without a doubt, I've got to say this just might be the best new music week in recent history!

Here are my picks for the top 5 new music must-downloads this week... (and yes, it's in a particular order-wink!)

I totally agree with all of your Daily Kiss comments last week that Simple Plan just has that way of capturing those exact emotions you're feeling in both their lyrics and music in songs like "Welcome to My Life" and "Untitled." So I'll be the first to admit, I was a tad nervous when I heard they were working with Timbaland's right-hand man Danga (he also worked on Britney Spears and Madonna's new albums!). But the guys stopped by the CosmoGIRL! offices last week with their freshly burned CD and as soon as they hit "play," we knew they were onto something spectacular!

Simple Plan has totally stepped up their game and reinvented themselves in a way that's so ground-breaking, it's hard to put into words. It's still the same ol' Simple Plan vibe with their catchy sing-along tunes and straight-out-of-your-diary lyrics--but with an edgy new twist that's the perfect natural progression for them. Don't worry, they didn't "sell out" to today's R&B trend--they've simply taken the best of the beats and integrated it perfectly into the Simple Plan style.

But since I'm having such a hard time describing it myself, why don't you take a listen for yourself? There's a 25-second clip of "When I'm Gone" on simpleplan.com--let us know what you think! And in true SP style, the guys are bringing the complete song to you themselves in an exclusive webchat on Monday, October 29, 2007 at 6 p.m. ET/3 p.m. PT to preview the entire song and chat with all of you about their new album, coming out January 29, 2008. If you're counting the days along with me, it's 94 days to go! Thank goodness we'll have "When I'm Gone" to tide us over starting Tuesday!

2-Backstreet Boys' new album, Unbreakable (out October 30)

Boy, did we have a debate on the Daily Kiss a month ago about whether or not there was room for boy bands in today's music scene, but with the success of "Inconsolable," I think the answer is clear. When I talked to the guys a couple weeks ago (come back to our celeb Q&A page next week for the interview!), they said this time the goal was to go back to what people expect from them-- no more fussing around and experimenting with new sounds. And it works for them. Rivaling old favorites like "Incomplete" and "Shape of My Heart" are drop-to-your-knees ballads, like "Unmistakable" and "Love Will Keep You Up All Night."

But that doesn't mean it's just more of the old sound regurgitated over and over. There's definitely an element of growth that shows in songs like "Panic" (perfect song for the treadmill!) and "Unsuspecting Sunday Afternoon" (something about this tune just tugs at your heartstrings).

My favorite picks for this album? Hmm... definitely quite a few radio hits on this one. "Trouble Is" has a tinge of a country vibe to it, but is just one of those songs you can't get out of your head. "Something that I Already Know" is so classic BSB, that you can't help but love it. But I think my top pick may have to be "You Can Let Go." It may be one of the most perfectly-crafted songs I've heard in a long time. When it came on shuffle on my iPod, I was surprised to see it was Backstreet Boys. All I can say is... Backstreet's Back... and that's a good thing! :)

I know, I know. Am I serious? Britney?! But I beg you to give her a chance. I still prefer classic Britney with "Sometimes" and "Lucky" (yes, guilty!), but despite all her personal-life drama, this girl does know what she's doing on the music front too. Blackout is definitely an extension of her last album--primarily songs you'd hear on the dance floor, but at least she knows what she does best.

Some of the song titles are a little more "fitting" to her personal life today (cases in point: "Why Should I Be Sad" and "Freakshow"-ha!), but the fact is, she's got the right hooks, and every song makes you want to get down. Even if you try to resist, you'll be bobbing your head to songs like "Perfect Lover" and "Hot as Ice." And yes, there's a song called "Get Naked (I Got a Plan)," but everything aside, there's something to it!

Plus Britney knows how to fit into the current music scene. Timing it with Backstreet Boys' release, it's a 1990s flashback! Putting it next to Simple Plan, they both have Danga's magical musical touch. Check out a few songs, and I'm sure you'll be buying the whole album in no time!

So many people judge these guys and lump them as just another "Disney" act, but the Jonas Brothers are so much more than that. You guys showed your Jonas love earlier this summer when their self-titled sophomore album came out August 7. But what I personally find so cool about the Jonas Brothers is that they can play alongside bands like My Chemical Romance and Plain White Ts at shows like Bamboozle... and on my iPod, I shuffle them with all my favorite rock bands (like Rooney, Simple Plan, Relient K, Green Day)--and am often shocked when I look down and realize it's actually a Jonas song!

This re-release will contain all the TRL and Billboard charttoppers like "S.O.S." and "Hold On." One of my other favorites is "Goodnight and Goodbye," which I call Fall Out Boy Lite! And there's something so fun about "That's Just the Way We Roll," that I make a point to play it every morning on my way to work to put me in the right mood! Oh, and how can you not get a little "Hey There Delilah"-like shiver whenever you hear "Hello Beautiful?!"

The bonus edition will contain two new tracks: "Take a Breath" and "We Got the Party" (it's a duet with Miley Cyrus, how can you go wrong?!) and a DVD with four music videos, exclusive concert footage, and a photo gallery. Come on, you can't resist, can you?

5-Taking Back Sunday's new album Notes from the Past (out October 30)

If you're not familiar with Taking Back Sunday, this is the perfect intro album for you. It's a compilation of the band's first two albums, Tell All Your Friends from 2002 and Where You Want to Be from 2004. And they also throw in a couple b-sides even diehard fans may not have heard before. There's "The Ballad of Sal Villanueva" from a special edition of Tell All Your Friends and "Your Own Disaster" from a Japanese special edition.

Taking Back Sunday definitely skates that line between a My Chemical Romance or Panic! At the Disco sound and more of a Good Charlotte or Fall Out Boy vibe. But either way, they never go wrong. How can you when you've got a song with as clever of a title as "Cute Without the 'E' (Cut from the Team)?" And the hooks in "You Know How I Do" are so catchy, you'll instantly hit replay.

Whew! That's a lot of new music to squeeze into one week in between trick-or-treating and haunted houses (I'm still screaming from the one I just got back from! Thank goodness of I have all this new music to calm me down!).

Which of these are you most looking forward to this week? And come back after they've come out and tell me which were your faves!
